Description

Title: Nozzle Descrirtion of Invention This invention relates to a nozzle for conveying a viscous liquid. The invention is described in relation to a dispensing nozzle for dispensing viscous liquid from a storage tube thereof.
There are numerous fluids in the form of gels, viscous liquids, and flowable polymers commonly used today for a number of different purposes. For example, adhesives are used to bond surfaces together, a number of gels are used in the medical field, and caulking material is used in the building trade to seal areas where solid materials join, to make them air and/or watertight. All such substances are referred to herein as "viscous liquids". It is common for these to be stored in a tube, and for them to be dispensed by increasing pressure upon the contents of the tube. For example, the tube walls may be compressed to decrease the internal volume of the entire tube, or a piston may be disposed at one end of the tube and may be displaced axially to decrease the internal volume of the tube available to the viscous liquid. Alternatively, a pneumatic applicator may be used, which forces air (or another propellant gas) into the storage volume of the tube to displace the viscous liquid from the tube, or to actuate a piston to do the same.
A storage tube has an outlet through which the contents of the tube are dispensed, and it is common for a nozzle to be attached to this outlet, to direct the substance in question. In the case of caulking, or other such sealants, nozzles of various shapes and sizes are used. The nozzle controls the cross-sectional shape and dimensions of the dispensed liquid, and the point at which the liquid is dispensed relative to the outlet, and it can also affect the shape of the material as it leaves the tube. The form which the viscous liquid takes when it leaves the nozzle is often referred to as a bead'.
One such area where such sealant and nozzle arrangements are used is in the building trade, where sealants are used to seal construction panels and decorative panels within buildings. For example, in a building it is common for there to be sealant provided between a number of joints in the bathroom and kitchen, such as for sealing a sink unit to a kitchen surface, or sealing skirting boards or tiled surfaces at right angle joints. Such viscous liquids may also be used in difficult-to-access areas, such as sealing around pipes and taps within a kitchen or bathroom. Similarly, in the automotive industry, it may be desirable to dispense a viscous liquid, such as a grease, to a difficult-to-access part of a vehicle. As most prior art nozzles are fixed in one position, and extend in an axial direction from the tube, they are poorly adapted to allow a user to deliver the viscous liquid in question to difficult-to-access work areas.
A repositionable nozzle which seeks to overcome this problem has been proposed, comprising three main components -a base part which connects to a storage tube, an extender part which joins to the base part, and a dispensing part which connects to the extender part, and includes the nozzle outlet for dispensing the viscous liquid. Each part includes a passageway, and the parts connect to each other in a manner which allows fluid communication between their respective passageways, and hinders or prevents any viscous liquid from leaking at the point at which the parts join together.
The base part is adapted to connect to a storage tube at its lower end, and has a hollow frusto-spherical ball formation at its upper end. The extender part is provided with a part-spherical socket formation at its lower end, and a hollow frusto-spherical ball formation at its upper end, and the dispensing part has a part-spherical socket formation at its lower end and an opening at its upper end.
The part-spherical socket formation is dimensioned such that it engages the hollow frusto-spherical ball formation in an interference fit, and it may be a snap fit arrangement. Once engaged, the part-spherical socket can rotate about the frusto-spherical ball formation, allowing the parts to pivot relative to one another. The formations may be separated from one another after being fitted together, and can be reconnected if necessary, such that the parts can be used as a kit of parts for achieving various configurations as required. The parts can therefore be assembled to achieve a number of different lengths of nozzle, and the nozzle can be pivoted as required to achieve a great number of angles. The fitment of the parts to each other also resists the straightening effect of the viscous liquid passing through it, which allows the user to dispense the liquid to the desired area in a controllable manner.
There are several issues with the nozzle arrangement discussed above. As the opening of the nozzle is of a fixed cross-sectional area, each dispensing part can only be used to achieve a single bead thickness, which means that multiple dispensing parts must be made, to allow a range of bead thicknesses to be achieved.
However, having multiple dispensing parts is an undesirable solution, as these must then be carried by the end user, and also fitted to the nozzle. For a repositionable nozzle, the dispensing part must be relatively small to get into restricted spaces, and an end user is likely to find a small component difficult to handle and fit.
There are also issues associated with the base part of the nozzle. Different sized storage tubes have different sized outlets, so the base part of a nozzle is dimensioned to fit one particular size of storage tube outlet. For the reasons discussed above, the need for a number of different base parts also has an undesirable effect.
Embodiments of the present invention seek to ameliorate one or more
problems associated with the prior art.

Figure 11 shows a further connector part incorporating aspects of an embodiment of the invention, in a second position.
Referring now to the drawings, a nozzle part is shown at 10. Wherever nozzle parts are shown in the drawings, it will be appreciated that the nozzle part may be a complete nozzle, a portion of a larger nozzle part, or one component of a kit of parts which are joined together to make a complete nozzle.
Nozzle part 10 has an inlet 12, and an outlet 16, and fluid communication between the inlet 12 and outlet 16 is afforded by a passageway 20, which is defined by wall 28. The passageway 20 has a cross sectional area at a region 14 towards its inlet 12 larger than its cross sectional area towards its outlet 16.
A portion 18 of wall 28 adjacent the inlet 12 is shaped to enable its connection to other parts. For example, it may have a screw thread formation on the inner or outer face of the wall, or formations which form part of a bayonet fitting, or may be shaped for another mode of engagement with another part. In the example shown, the wall is shaped to form a part-spherical socket, to receive a hollow frusto-spherical ball-shaped element, to enable the nozzle part 10 to be pivoted about this element.
The nozzle part 10 is provided with indicators 22 and 24, which in the example shown in figure 1 are in Ihe form of markings visible from Ihe oulside of wall 28. These may be in the form of markings which are raised from the surrounding wall, markings which are flush with the surrounding wall, or markings which are indented relative to the surrounding wall, and the indicators may extend around all, or part of, the wall 28. The indicators 22 and 24 may be used to mark areas which could be of significance to the user.
For example, they may be used to denote a certain distance from the outlet 16 of the nozzle part 10, which may be useful for helping the user position the nozzle, such as when assessing nozzle depth when inserting the nozzle into a hole. The indicators may also be used to denote a certain cross sectional area at the point marked. This would be useful to a user who wants to modify the nozzle 10, so that Ihere is a larger cross seclional area al the oullel 16 Ihan originally supplied. This allows a single nozzle to adapt for use in a number of different scenarios; a nozzle part 10 with a 2mm diameter outlet could be adapted to have a 4mm diameter for example, and/or a 6mm diameter. This would allow the user to keep one type of nozzle in their tool box, and adapt it for different purposes. For example, the user may cut the nozzle part 10 using a tool such as a chisel, saw, a knife, a pair of pliers, or a pair of scissors, and the nozzle 10 may be made of a material which can be cut easily, such as a suitable plastics material.
The indicators may extend around the perimeter of the wall 28, and may extend in a direction perpendicular to a longitudinal axis defined by the passageway 20.
Another similar nozzle part is shown at 30, and the nozzle part 30 is provided with indicators 32 and 34. In this case the indicators 32 and 34 are formed as grooves in the wall 28, and these may extend around all of or part of the wall 28. It will be appreciated that the cross-sectional area at C is greater than that at the outlet 16, but less than that at B. The grooves may be shaped to engage a blade, such that they hinder or prevent movement of the blade once the blade has been inserted into the groove, to assist the user in cutting the nozzle part cleanly. Alternatively, or in addition, the grooves may create a thinner wall 28, which makes it easier for the wall to be broken at that point.
The grooves may be provided with several other features, as well as, or instead of, the features listed above. The grooves may be provided with a sharp corner to act as a stress-raiser, which would make it easier for the user to break that section of wall. The grooves may not be identical, and may be adapted to result in a stronger or weaker wall relative to the next groove. For example, by providing a deeper groove without thickening the wall at that point, the wall would be thinner and more fragile than the wall at a shallower groove. This technique could be used to provide grooves which are progressively more difficult to break off, and this could be used to assist the user when modifying the nozzle to give a different outlet size. For example, the sections could be progressively more difficult to break off as the cross sectional area of the passageway increases in size, meaning that the user breaks off pieces one by one using an increasing amount of force. This can be used to minimise the risk of breaking off the nozzle at an undesired groove, resulting in an outlet with a cross sectional area larger than the cross sectional area desired.
Figure 4 shows another nozzle part 40, based upon similar principles to those discussed above. In this case, indicators in the form of grooves 42 and 44 are provided on the inner face of the wall 28, such that they would not be easily visible in use. However, as discussed above, the grooves may require progressively more force as the cross sectional area of the nozzle is larger, so if the user applies force to remove a section of wall to increase the outlet size, it is likely that the next standard size of outlet will be selected. Should the user wish to make the outlet size larger still, they can apply force to the nozzle again, until the next larger size breaks away.
Figure 5 shows a nozzle part 50, which has indicators in the form of steps defining corners 52 and 54. The corners can provide a clear visual indicator of a certain point of the wall, and also act as a stress-raiser, which increases the likelihood of the wall breaking at that point when a force is applied. The wall 28 may taper between the indicators 52 and 54, but the nozzle part 50 could alternatively be made with walls which do not taper between the indicators, such that the cross sectional area of the passageway towards the outlet changes in steps. The wall 28 may have a reduced thickness at the corners 52 and 54.
Figure 6 shows a nozzle part 60, which has indicators in the form of portions of relative weakness in the wall at 62 and 64. These may be made of a different material from the remainder of the nozzle 60, or may be the same material which has been weakened, such as by heat treatment, UV light treatment, or by the material having a different structure at those points.
It will be understood that any of the indicator features discussed above may be combined. For example, a nozzle part could be provided with a groove on the outer surface of its wall and on the inner surface of its wall, and the remaining wall at the base of each groove could also be weakened. Similarly, there could be one indicator of one type for one groove, and a different type of indicator for the next groove. One such combination is shown in Figure 7, which shows a nozzle part 70 with a groove in the outer surface of wall 28 at 72a, and an area of weakness 72b in the wall under the groove. There is a further groove in the outer surface of the wall at 74a, and a groove on the inner surface of the wall at 74b.
Referring now to Figure 8, a cutaway view of a connector 100 for connecting to a first fluid container llOa is shown, in a first position. Such a connector 100 may be used as a base part for a nozzle, and may be suitable for conveying a viscous liquid. The connector comprises a first connector portion 120, and a second connector portion 140.
The first connector portion 120 has a wall 132, and a flange portion 126. The flange portion may have an abutment face 122. An inner surface 136 of the wall 132 defines an axial passageway 138, and part of the inner surface of the wall is provided with an engagement formation 130. Although the engagement formation 130 shown in the drawings is a screw thread, any suitable engagement formation may be used, for example one for bayonet engagement, or a smooth or tapered inner wall which allows a transition or interference fit to be achieved.
The wall 132 extends to an outlet formation 134. The outlet formation may be shaped to function as a nozzle, or may be shaped to engage another part. For example, the outlet formation may provided with a hollow frusto-spherical ball-shaped element, for engagement with a part-spherical socket of a further part, which may enable the further part to be pivoted about this element.
The outer surface 124 of the flange portion 126 is provided with an engagement formation comprising a screw thread. The upper surface 128 of the flange formation 126 may be provided with a sealing means, such as a deformable seal.
The second connector portion 140 is substantially annular, and has a wall 150 with a flange portion 144. The flange portion 144 has an abutment face 142, which may abut the fluid container 110, in use. On the inner surface 148 of the wall 150, there is an engagement formation 146 in the form of a screw thread engaged by the screw thread on the outer surface of flange portion 126, and wall 150 extends to a shoulder portion 152. The engagement formation may extend to cover all or part of the inner surface 148 of the wall 150. The shoulder portion 152 has an inner surface 154, and this may be provided with a sealing means, such as a deformable seal.
When the connector 100 is in the first position, the first fluid container 11 Oa can be engaged by the engagement formation 130, and the contents of the fluid container can then flow into the axial passageway 138.
Referring now to Figure 9, the same connector 100 is shown, in a second position, connected to a second fluid container 11 Ob. The first connector portion 120 has been moved axially relative to the second connector portion 140. To move the connector 100 from the first position to the second position, the first connector portion 120 may be moved along the engagement formation, such as by rotating the first connector portion relative to the second connector portion where the engagement formation 146 is compatible with an engagement formation provided on the outer surface 124 of the flange portion 126. Alternatively, where there is not a compatible engagement formation provided on the outer surface 124, the first connector portion 120 may simply be moved manually, or moved by the ingress of the container 11 Ob into the first connection portion 140.
In the arrangement shown in figure 9, the upper surface 128 of flange 126 is in contact with the inner surface 154 of shoulder portion 152. These portions may be retained in close liquid tight contact with one another, and the deformable seals which may be present on one or each of these may be deformed to achieve this. The movement of the second connector portion allows space for the second fluid container 11 Ob to be engaged by the engagement formation 146. In the second position, viscous liquid from the second container hUb may be permitted to flow into the passageway 138.
It will be appreciated that modifications may be performed to the above described arrangement without departing from the scope of the invention. For example, the outer wall surface 124 of the flange portion 126 may seal to the inner wall 146 of the first connector portion 140, so the upper surface 128 of the flange 128 does not have to be in contact with the inner surface 154 of the shoulder portion 152 to be used in the second position. Similarly, additional connector parts could be provided which would allow a greater number of container outlets to be engaged. For example, another connector portion may be provided around the outer surface of connector portion 140, such that the connector portion 140 is in the same relationship with the new connector portion as the second connector portion 120 is with the first connector portion in the drawings.
An example of another connector incorporating aspects of an embodiment of the invention is shown in Figure 10. The second connector portion of the connector 200 is connected to second fluid container 11 Ob, and the first connector portion 250 is elongated to provide a nozzle formation, which is provided with indicators in accordance with aspects of embodiments of the invention. This demonstrates one possible combination of the features described above, but it will be appreciated that any compatible features described above may be combined without departing from the scope of the invention.
Extender parts may also be used with the nozzle part and connector described herein. An extender part may comprise one engagement formation disposed at an inlet end, another engagement formation at an opposite end, and a wall defining a passageway therebetween. The engagement formation at the outlet end of an extender part may be adapted to engage with the engagement formation at the inlet end of an extender part, enabling several extender parts to be connected to one another.
For example, the engagement formation at the inlet end may be a part-spherical socket element, and the engagement formation at the outlet may be hollow frusto-spherical ball-shaped element. This would enable a number of extender parts to be connected consecutively, and each extender part to be pivoted about the hollow frusto-spherical ball-shaped element received at or adjacent its inlet.
The part spherical socket element at the inlet of an extender part may be engaged with a frusto-spherical ball-shaped element provided at or adjacent the outlet of first connector portion 120 of the connector part 100. Similarly, the hollow frusto-spherical ball-shaped element provided at the outlet of the extender part may be engaged with a part-spherical socket provided at the inlet of a nozzle part. Using this principle, a number of extender parts may be used to provide the required nozzle assembly length, and the parts may be pivoted to achieve the desired nozzle outlet position. A number of the parts described may be provided in a kit, to allow the user to achieve a number of different nozzle assemblies.
An example of another connector incorporating aspects of an embodiment of the invention is shown in Figure 11. The second connector portion of the connector 300 is connected to second fluid container 1 lOb, and the first connector portion has an engagement formation 310 at the outlet in the form of hollow frusto-spherical ball-shaped element. A nozzle portion generally indicated at 320 is provided with a part-spherical socket which is engaged with the engagement formation 310. An extender part 400 is also shown, which includes an engagement formation 410 at the outlet in the form of hollow frusto-spherical ball-shaped element, and a part-spherical socket 418. It will be appreciated that the part-spherical socket 418 could be engaged with the engagement formation 310, or an engagement formation 410 of another extender part 400. The user could therefore connect one extender part 400 to a connector 300, connect any further number of extender parts 400 to that extender part, before fitting a nozzle part 320 to the remaining available engagement formation 410 of the endmost extender part. Using this method, a number of different assemblies could be achieved by using different numbers of extender parts. As each part-spherical socket can pivot about each hollow frusto-spherical ball-shaped element, an assembly with a number of extender parts can be pivoted at each joint, enabling a number of different configurations of nozzle to be achieved.
When used in this specification and claims, the terms "comprises" and "comprising" and variations thereof mean that the specified features, steps or integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
